I put new card in my Pc. It is a Verto by PNY NVIDIA GeForce 7600 GS AGP 8X 512MB DDR2. Now some henchmen and a lot of AI's are in some kind of loop where they jump forward over and over. They start out standing then they hop forward and then into a bent over kind of kneel. The loop keeps going on forever. This dose not effect game play. But is a pain in the ass to watch.
try taking the card out and reseating it in the slot. The try installing the latest drivers and make sure you have the latest DX9 installed. Other than that, maybe try messing with the visual options in game
Same problem happened to me. It's not related to your video card in any way. Your Gw.dat file got corrupted. If a reinstall doesn't work (didn't work in my case), delete your Gw.dat file manually and download a new one.
Thank you for all your input. The bad thing is I can only get dial up Internet where I live. My data file is almost 4 gigs It would take a month to download it again. So I will have to live with the problem for now.
